Massive upper gastrointestinal bleeding from an accessory splenic artery mimicking isolated gastric varices.

Knowledge of anatomical variations of coeliac trunk and its branches is important for surgeons and interventional radiologists planning surgical and radiological interventions. We describe a case of a 42-year-old male with an accessory splenic artery (ASA) originating from the left gastric artery (LGA) running in the wall of gastric fundus and mimicking isolated gastric varices, which was observed during endoscopy. Bleeding from this artery was massive and was managed with endovascular coil embolisation. Coeliac angiography of the patient with upper gastrointestinal bleeding showed that the coeliac trunk divided into 3 arteries: the LGA, the splenic artery, and the right hepatic artery. Additionally, the variations of ASA and the left hepatic artery arising from LGA, and the left and right inferior phrenic arteries arising from ASA were identified. This case is the first to be presented in the literature with ASA originating from LGA that was situated in the gastric wall where inferior phrenic arteries arose from the ASA.

Endovascular angioplasty-stenting as a definitive treatment for isolated spontaneous common carotid artery dissection. A case report.

Isolated spontaneous common carotid artery (CCA) dissection is rare. So far, surgical or medical treatment have only been reported in a few cases in the literature. We report a 39-year-old man, diagnosed as isolated spontaneous CCA dissection one year ago, who experienced a new minor stroke despite medical treatment. Because of the presence of new ischemic lesions on new magnetic resonance imaging despite medical treatment, and critical narrowing of internal carotid artery (ICA) orifice with jet and turbulence flow pattern at the bulbar portion of the ICA, endovascular management was performed with carotid stent deployment. To the best of our knowledge, this is the first case of spontaneous isolated CCA dissection treated with stenting of the carotid artery reported in literature. - ÖZET - Izole spontan common carotid arter (CCA) diseksiyonu nadirdir. Literatürde sadece birkaç adet, medikal veya cerrahi tedavi uygulanan, CCA diseksiyonu olgusu bildirilmistir. Bildirimizde, bir yil önce izole spontan CCA diseksiyonu tanisi almis ve medikal tedavi altinda iken yeni minor strok geçiren 39 yasinda erkek olguyu sunuyoruz. Olgunun yeni magnetik rezonans görüntülemesinde (MRG), sol posterior frontal ve pariyetal loblarda yeni iskemik lezyonlarin ortaya çiktigi görüldü. Renkli Doppler ultrasonografi (RDUS) incelemesinde eski incelemesine gore darligin arttigi izlendi. Karotis anjiografide de internal karotis arter baslangicinda jet ve türbülans akima neden olan kritik darlik saptanmasi üzerine endovasküler tedavi planlandi. Femoral girisimle koruyucu filtre kullanilarak self ekspandibl stent yerlestirildi ve postdilatasyon balon uygulandi. Islemden 24 saat sonra alinan difüzyon MRG incelemesinde yeni iskemik alan görülmedi. Birinci ve 3. ay kontrollerinde, nörolojik muayenesinde yeni bulgu saptanmadi. RDUS incelemelerinde stentin açik oldugu görüldü. Karotis artere stent yerlestirimesi cerrahiye alternatif bir tedavi olup daha az invazivdir. Stent uygulamasi, spontan ve travmatik internal karotis arter darliklarinda kullanilmis, ancak izole spontan CCA diseksiyonunda kullanilmamistir. Olgumuz nadir görülen izole spontan CCA diseksiyonu olgularindan biri olup stent yerlestirilerek tedavi edilmistir. Sonuç olarak, medikal tedaviye ragmen tekrarlayan semptomlari olan izole spontan CCA diseksiyonu olgularda tromboemboli kaynaginin kontrol altina alinmasi ve yeterli karotis akiminin saglanmasi için stent yerlestirilmesi gerekebilir.

Duplex sonography of the carotid arteries in patients with pure aortic regurgitation: pulse waveform and hemodynamic changes and a new indicator of the severity of aortic regurgitation.

PURPOSE: To determine the changes of multiple hemodynamic parameters and pulse wave contour in pure aortic regurgitation (AR) and to present a new indicator of the severity of AR (shrink ratio of proximal common carotid artery). MATERIAL AND METHODS: The sonograms of 42 patients (31 M, 11 F; 16-68 years) with pure AR and 18 control subjects (15 M, 3 F; 20-47 years) were assessed for velocities and indices, and change of pulse wave contour (bisferious pattern, zero level and retrograde diastolic flow) in each carotid artery. Shrink ratio (maximum diameter-minimum diameter/maximum diameter) of each proximal common carotid artery was calculated. RESULTS: Bisferious waveforms seen in patients with AR grade 1, grade 2, and grade 3-4 were 66%, 83%, and 88%, respectively. Diastolic reversed flow was determined in 7 (39%) of 18 patients with AR grade 3-4. Three patients (25%) with AR grade 2 and 4 patients (22%) with AR grade 3-4 had zero level diastolic flow in the common carotid artery. Statistically significant changes of decreased end-diastolic velocity, increased peak systolic velocity/end-diastolic velocity, resistivity index, and pulsatility index were revealed, especially in AR grade 3-4 compared to controls. Significantly increased shrink ratio was seen only in AR grade 3-4. CONCLUSION: Increased shrink ratio or changes in hemodynamics or pulse waveform can be used in recognition of AR.

Assessment of mastoid air cell size versus sigmoid sinus variables with a tomography-assisted digital image processing program and morphometry.

We assessed the mastoid air cell size and variables of the sigmoid sinus in healthy ears and ears with chronic otitis media (COM). Thirty-eight patients with unilateral COM [15 with cholesteatoma (COM/+) and 23 without cholesteatoma (COM/-)], and 20 subjects with healthy ears, were included in the study. Assessment was performed using a quantitative digital image processing computed tomography (CT) program, and the volume of the mastoid bone was measured using the morphometric method of Cavalieri. In both COM/+ and COM/- patients the sigmoid to suprameatal spine distance and mastoid size were greater on the healthy side than on the diseased side ( p<0.05). The distance and area were significantly greater in the healthy control subjects than in either the healthy or the diseased ears of the patients with COM ( p<0.05). In the healthy ears of COM patients, there was significant correlation between the sigmoid to suprameatal spine distance and air cell size and mastoid volume ( p<0.05). In the diseased ears of COM patients, this correlation was absent ( p>0.05). The sigmoid sinus shape was of the half-moon type (62%), protrusive type (22%) and saucer type (16%). The digital image processing CT program allowed us to estimate the individual area of the air and soft tissue filled mastoid air cells. The mastoid size in both intact and disease ears of COM patients was smaller than in the healthy controls. The mastoid size may be determined genetically. However, environmental factors such as infection may also affect the mastoid size. Therefore, both genetic and environmental factors may be related to COM as far as the size of the mastoid air cells is concerned.

Carotid and brachial intima-media thickness, arterial diameter and resistivity indices in aortic regurgitation.

PURPOSE: To evaluate signs of atherosclerosis in carotid and brachial arteries in patients with aortic regurgitation (AR). MATERIAL AND METHODS: The sonograms of 33 patients (24 M and 9 F, 16-67 years old) with pure AR and 20 control subjects (15 M and 5 F, 19-49 years old) were evaluated. Patients with AR and control subjects completed a questionnaire with SMART risk score based on pre-existing vascular disease and risk factors. AR patients and control subjects were assessed for intima-media thickness (IMT) of common carotid artery (CCA), IMT of brachial artery (BA), CCA diameter, and resistivity index (RI) of CCA and RI of internal carotid artery (ICA). RESULTS: There was no significant difference in the cardiovascular risk score between the patients with AR and control subjects. All measured parameters were statistically significantly greater in AR patients than in control subjects with P values 0.0233 for CCA IMT, 0.0034 for BA IMT, 0.0429 for CCA diameter, <0.0001 for CCA RI, and 0.0002 for ICA RI. CONCLUSION: AR is associated with signs generally considered to represent atherosclerosis, such as increased CCA and BA IMT, CCA diameter, and CCA and ICA RI.
